The paper presents the application of spectral method to non-linear random vibration problems in offshore engineering. In the case of structures like single point mooring systems, the non-linearity comes from the non-linear restoring coefficient of mooring lines. The response spectrum for the non-linear dynamic response of the structure is studied by introducing the Hermite polynomial. The method provides an efficient tool for analysing moored structures.
